This is related to
REST should be able to provide the default value just by given the ConfigBean type, eg. jdbc-resource, thread-pool, virtual-server etc.
But currently unless this attribute is one of the create command param, it cannot do that.
The limitation is that not all default value is available unless the instance is created first.
Want to request REST to provide a way to give all the default value of any attributes without requiring:
1. the attribute be one of the params for create command
2. the resource has to be created first to be able to get those default value.
